LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 298,011l dated May 6,1884.

Application filed October 23, 1883. (No model.)

To all whom, it may concern Be it known that I, GEORGE MGNEIL, residingat Chicago,l in the county of Cook and State of Illinois, and a citizenvof the United States, have invented new and useful Improvements inLubricators, of whichl the following is a full description, referencebeing had to the accompanying drawings, in which- Figure 1 is a sideelevation; Fig. 2, a section on line :r of Fig. 1, showing thefeed-valve for the oil or lubricant; Fig. 3, a section on line y of Fig.2; Fig. 4, a transverse longitudinal section through the chamber for thepassage of the steam and oil; Fig. 5, a vertical longitudinal section;Fig. 6, a'detail showing the pressure-pipe applied to the end of the amodiiication of the filling-plug. p

This invention relates to that class of lubricators in which the oil isforced and fed from the reservoir by the pressure of a column of water,and has for its objects to simplify the construction and improve theoperation of this class of lubricators, as hereinafter more fullydescribed; and its nature consists in the several parts and combinationsof parts hereinafter described, and pointed out-in the claims as new. Y

In the drawings, A represents the reservoir for the oil or otherlubricant, which may be made in a cylindrical form, of brass or othersuitable material, or may have a body of glassV and ends of any suitablemetal, as may be dc- Sired.

B is the pipe for the water of condensation, which furnishes thepressure required for feeding the oil or other lubricant. The dischargeend of this pipe, as shown, is contracted at B', to increase the amountof pressure from the Water in the pipe; but, if desired, this pipe B maybe of the same diameter its entire length.

C is a connecting-pipe, of smaller diameter than the pipe B, to thedischarge end B of which pipe it is connected by an elbow, a, andavpipesection, a', in the formof construction shown; but the connectionmay be made in some other suitable manner. This pipe O is provided witha valve-chamber, C', for the rcception of a suitable valveto control thefeed through the pipe C, which valve is operated by a hand-whee1,C,.orin some other suitable .tral opening, c, from which a passage, c', leadsin a diagonal direction, as shown, and com municates with a transversepassage, c, in which is arranged a valve, d, the stem d of which isscrew-threaded, and passes through a stuffing-box on'the side of theplug in the usual manner, and `is operated by a' hand- Wheel, d. Thisvalve d controls the opening into a discharge-nozzle, e, which nozzlecommunicates at its lower end with the transverse passage c, so that theoil or other lubricant will pass into vthe opening c, thence into thepassage c to the passage c, and into the discharge-nozzle'e.

F is a tube of glass, through which the oil passes to the point ofdischarge, the tube being made of glass in order to observe whether thefeed is working in a correct manner. This tube at its lower end' islocated around the feed-nozzle e, as shown in Fig. 3, and is held inplace and connected with the plug E by entering an opening in a nippleof the plug,

which'nipple receives a suitable stuffing-box.

G is a chamber, made of brass or other suit,- able material, and havinga transverse opening, f, which, when the parts are together, comes inlinewith the opening in the plug E, for the reception of the glassfeed-tube F, so

that such feed-tube can be inserted in position.

and on the side of the chamber G, around the The opening f is closedby asuitable plug, f', j

openingf, is a screw-threaded nipple, f, to 'l receive a stuffing-boxand make a tight joint around the feed-tube F. The chamber G is jprovided with two longitudinalY openings, g

and g', one of which, g, extends from one endl of the chamber nearlyV tothe opposite end in 1 one form of construction, and `the other, g',

extends from the end ofthe chamber to the"y opening f. The opening gpasses around the TOO opening f, as shown in Fig. 4, and communicateswith a pipe, l1', which pipe extends into the pipe B, and is bent aroundso as to form a U-trap, and this opening or passage g is for the passageof the steam from the steam-pipe to enter the pipe h, and pass therefromin the form of spray and be condensed and iill the pipe B with thiswater of condensation. The other opening, g, is provided with a pipe,h', which, as shown, is curved downward, which pipe,when the parts aretogether, comes inside of the steam-pipe, to which the chamber isconnected, the chamber at the supply end, as shown, having ascrew-threaded nipple for the purpose of making the connection with thesteam-pipe.

H is a standard, one end of which rests on the Atop of the reservoir A,and is connected therewith by screws or in any other suitable manner,and the other end of which enters a boss formed on the under side of thechamber G. This standard H furnishes a support between the chamber G andreservoir A, and is for the purpose of giving greater rigidity to theparts when connected together.

I is a plug or stopper which enters an opening in the top of thereservoir A, through which opening the reservoir can be filled with oilor other lubricant.

J is a draw-off cock attached to the bottom of the reservoir A, throughwhich the sediment can be drawn oli' and the reservoir emptied, ifdesired.

The operation is as follows: The device is attached to the steam-pipe byconnecting the supply end of the chamber, G with the steampipe throughthe screw-threaded nipple on the end of the chamber, or in any othersuitable manner, the pipe h being in the opening g' and passing into thesteam-pipe. The steam passes into the opening g, thence into the pipe h,where it is condensed, and passes in the form of spray into the pipe B,passing out at the discharge end B ot' such-pipe into the pipe C, andfrom this into the pipe D and into the chamber A; and the amount ofwater which passes through the pipe C and enters the reservoir A isregulated by the valve in the chamber C. The water as it enters thechamber A displaces the oil or other lubricant in such chamber, whichpasses into the opening c, thence through the openings c c into thenozzle e, from which it passes into the feed-tube F to the opening g',and through the pipe h into the steam-pipe, for lubricating purposes,and the amount of the feed for the oil or other lubricant is controlledand regulated by the valve d.

The device is very simple in construction,

as it consists, essentially, of a reservoir or rechamber for the passageof the steam from the steam-pipe to the feed-pipe, and for the passageof the oil from the oil-feed tube to the steam-pipe, and by thisconstruction it will be seen that only two valves are necessaryone forcontrolling the passage of the water of condensation to the reservoir orreceptacle, and the other for controlling the feed of the oil or otherlubricant.

It will be further noticed that by the construction shown and describedthe passage for the steam and the passage for the oil to the steam-pipeare wholly disconnected and have no communication with each other, theresult being that neither passage is in any manner affected by theother, leaving both passages free to do their required work withoutinterfering with each other. The construction also enables a readyremoval of the feed-tube for the oil to be had, for the purpose ofcleaning or otherwise, to do which all that is required is to loosen thestufling-boxes on the chamber G and plug E, which surround the oilfeedtube, and remove the plug f', when the feedtube can be pushed throughthe opening f and be removed, and when cleaned the tube can be insertedthrough the opening f, and the stuffing-boxes tightened and the plug finserted, when the device is again ready for use.

As shown, the reservoir, when the device is in position for use, isadjacent to the steampipe, and by this arrangement suticient heat isgenerated to keep the oil or other lubricant in the reservoir in propercondition to be fed through the pipe F, and it will be further seen thatthe oil or other lubricant must pass from the tube F through the passageg in the chamber G, and the steam for supplying the water ofcondensation also passes through this same chamber, the result beingthat the passage for the oil is kept sufficiently heated to prevent anysticking or adhesion of the oil or lubricant in its passage to thesteam-pipe.

If desired, a check-valve could be provided, as shown in Fig. 4, bymeans of which the flow of the oil or lubricant to the passage g couldbe shut oif, and a similar valve could also be provided for the passageg, by means of which the steam could be shut off from the pipe B.

Instead of having the filling-plug I located on top of the reservoir A,such plug might be located ou the side of the plug E, as shown in Fig.7, communication being had with the interior of the reservoir throughthe openings c c.

As shown, the pressure-pipe B is attached to the side of the chamber G 5but such pipe could be attached to the end of the chamber, as shown inFig. 6, a suitable stuffing-box or coupling being used, and when soattached the passage g should extend entirely through the chamber G, soas to have communication with the pipe B, and the trap h can bedispensed with. This trap h can also be dispensed with, if so desired,when the connection of the pipe B is made as shown in Fig. 5.

If it is desired to blowout the oil-receptacle and oil-feed pipe, it canbe readily done by IOO IIO

opening the ,discharge-valve of the receptacle and shutting off thesteam from the passage g, causing it to pass into the passage g, andthence into the oil-feed pipe F and reservoir, and when the reservoir iscleaned or blown oft' it can be refilled and made to operate, as Ybefore described, by closing the dischargeval've of the reservoir andallowing the steam to pass to the pipe D.

`What I claim as new, and desireto secure by Letters Patent, is asfollows:

1. The chamber G, having a passage, g, for steam and a passage, g', forlubricant, in combination with a pipe, B, for the water of condensation,reservoir A, having communication with the pipe B, and oil-feed tube F,substantially as and for the purposes specified.

2. The chamber G, having a passage, g, for

steam and a passage, g', for oil, in combination with the pipe B,trapipipe h, reservoir A, communicating with the pipe B, and feed-pipevF, substantially as and for the purposes specified. Y

3. The reservoir A and' plug E, having an opening, c, andpassages c c,in combination with the feed-tube F and feed-nozz1e e, substantially asand for the purpose specied.

4. The reservoir A, pipe B, having thetrappipe h located therein, andfeed-pipes C D, in combination with the plug E, feed-piped?, and chamberG, having the passages g n', substa'- tially as and for the purposesspecified.
